rcdklibs: The CDK Libraries Packaged for R

An R interface to the Chemistry Development Kit, a Java library
for chemoinformatics. Given the size of the library itself, this package is
not expected to change very frequently. To make use of the CDK within R, it is
suggested that you use the 'rcdk' package. Note that it is possible to directly
interact with the CDK using 'rJava'. However 'rcdk' exposes functionality in a more
idiomatic way. The CDK library itself is released as LGPL and the sources can be
obtained from <https://github.com/cdk/cdk>.
